Possible Causes

Basket not sealing properly, Damaged or warped basket rim, Excessive oil or fatty foods producing smoke, Blocked exhaust path redirecting steam

How to Fix / Troubleshooting

Safety first: Use the air fryer in a well‑ventilated area. If smoke is thick or dark, unplug immediately.

Steps:

  • 1. Check food load: Avoid overfilling the basket or using large amounts of oil. High‑fat foods can generate significant smoke.
  • 2. Basket condition: Inspect the basket and pan for warping or damage that prevents proper seating. Replace if the rim is bent.
  • 3. Clean thoroughly: Remove all grease buildup from the basket, pan, and interior surfaces.
  • 4. Exhaust path: Ensure the rear exhaust vents are clear. Blocked vents can force steam out of unintended gaps.

Note: Some steam release is normal, but visible flames or heavy smoke indicate a serious issue; stop use and inspect for grease fires or heater damage.
